"What is it, Ralph?" questioned the other, going right along with what he was doing in order not to show that there was anything amiss.
"Don't act as if I was saying anything out of the common, Hugh," said the other; "but first chance you get, peep out of the tail of your eye at the broken window, and you'll find that we're being watched!"
CHAPTER IV
READING A "SIGN" BY TORCHLIGHT
Of course it gave the leader of the Wolf patrol a thrill when he heard this low warning from Ralph. You never would have known it, though, from any uneasy movement on his part.
He knew that the boy who had spent so much of his time in the woods, trapping the cunning little furry inhabitants in seasons gone by, would not alarm him needlessly. And so, watching his chance, Hugh managed to shoot a glance toward the opening without betraying the fact that he was particularly interested in that quarter.
As he did so, he was just in time to see a face vanish from view. In fact, he barely caught a fleeting glimpse of it, and yet Hugh felt perfectly sure that he had not alarmed the watcher in any way.
The cause of the unknown party's sudden withdrawal was speedily made plain. Bud seemed to be gasping, and immediately whispered hoarsely:
"Great guns! did you see that, fellows? As sure as my name's Bud Morgan there was a man peeking in at the window there! Honest Injun, there was!"
Undoubtedly the unknown visitor must have discovered Bud staring straight at him, and thought it high time to disappear.
